T a/ w/wm t may concern:

Be it known that We, MATTHEW GRISWOLD, .Ir.,and DAVID SHIELDS., citizens of the United States, residing at the city of Erie, in the county of Erie and State of Pennsylvania, have invented certain. new and useful Improvements in Gas-Stoves; and we do hereby declare the following to be a full,clear, and exact descriptionof the invention, such as will enable others skilled .in the art to which .it appertains to make and use the-same, reference being hadY tor the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.

Thisinvention relates to improvements in gas-stoves; and it consists, substantially, in constructing a shield around the burner in such shape that it not only protects the burner from lateral drafts of air, but at the same time operates. not only as a deflector for the aircurrents around the periphery of the burner, but prevents the heat therefrom from being radiated downward, and in construct-l ing the burner and grate so that they can be readily. removed from the stove when desired. These features of the invention, together withV others hereinafterdescribed, are illustrated in the accompanying drawings, in which- Figure 1 is a top or plan View of a section of a gas-stove top embodying this invention. Fig. 2 is a vertical section of the same on the line in Fig.v 1. Fig, 3 is an enlarged detail of a portion of the stove-top and shield, showing the slot in which the removable grateAV is secured. Fig. et is-an enlarged detail of a portion of the removable grate, showing the lug thereon for engaging in the slot shown in vlar space or opening F between the lower edge of the shield or deflector D and the periphery of the burner E to allow the air to pass up around the periphery of the burner, as clearly illustrated by the arrows f f in Fig. 2.

The ring C, it will be observed, is cast upon the under surfaces of the inner ends of the arms b, so as to admit of a round grate G bein gplaced thereon, so that the upper surface A and the arms b, as is clearlyl shown in Fig. 2. In opposite sides of the ring C are vertical slots c, which extend down into the upper edge of the shield or deflector D, and joining thereto are lateral extensions d of said slot in the upper edge of the shield or deflec- 4.tor D, and on the ring forming the periphery of the grate G are lugs g, adapted to pass down vthrough the slot c and as the grate G is rotated pass into the lateral extensions d of said slots, so as to iirmly hold the grate G from being lifted out of place, these features being clearly illustrated in Figs. 3 and 4. Through the shield D, at each side, there are also cut narrow slits d', which substantially vide for the expansion and contraction thereof when heated and cooled and prevent the breakage of the parts from undue strain thereon.

The burner E is made circular in form and throughjwhich air can be supplied to the central part of the iiame,fas illustrated by the arrow ein Fig. 2.

To one side of the burner E is secured an arm e', adapted to drop into a pocket d2 in the shield or deflector D, and on the opposite side of the burner E there is an inlet-pipe II, the outer end h of which fits into a socket I on the inner end of an 'air and gas mixer J, secured to one side of the stove, s o that by raising the arm e out of the pocket d2 the burner can at once be removed from the stove. The air and gas mixer .I is of the usual and ordinary construction, except that it is prorotated so as to increase or diminish the size ofithe aire-inlet openings j, as may be desired. This air and gas mixer is also supplied with an ordinary shut-off cock K between' it and the gas-supply pipe L in the usual manner.

Having thus fully described this invention,

provided with a central opening E therein,

thereof will be on a level with the stove-top separate the shield D into two halves to pro- Jvided with a rotating shield J', which may be f IOO ward and inward therefrom, and an annular gas-fuel burner under said grate and Within said deeetor, substantially as and for the purpose set forth. 15

In testimony whereof We affix our signatures in presence of two Witnesses.
